FOLDING BED Filed Oct. 25, 1950 Patented Dec. 16, 1952 UNITED STATESPATENT OFFICE FQLDING BED Giite Y, M. Giipert, Jonkoping, SwedenApplication October 25,, 1950, Serial No. 192,022 In Sweden June 26,1950 4 Claims.

This invention relates to a folding bed, suchas a sofa or a chair,having a main frame comprising two end portions and a back portionconnected thereto and a bed frame comprising a number of sectionshingedly connected to each other. A folding bed of this type isdescribed in my simultaneously filed patent application Serial No.192,023.

An object of the invention is to provide a folding bed of the type setforth in which an end section of the bed frame is supported in a simpleand rigid manner when the bed frame is unfolded. Another object of theinvention is to arrange the end portion of the main frame and the endsection of the bed frame in such a manner that a locking device of asimple construction may be used which is easy to operate and forms noobstacle when released.

These and other obj ects and advantages of the invention will be fullyunderstood from the detailed description hereafter, reference being madeto the accompanying drawing in which:

Figure 1 is a diagrammatical end elevation of a portion of the foldingbed according to one form of the invention showing the supports for theend section of the bed frame inclusively the locking device.

Figure 2 is a corresponding elevation view of the locking device turned90 and lowered together with the end section to an undermost position.

Figure 3 is a top view of the device shown in Figure 2.

The main frame of the piece of furniture comprises two end portions madeof a metal tube and having a substantially vertical frame member I and asubstantially horizontal frame member 2 welded to the member I. The backportion of the main frame is parallel to and is covered by frame memberI in Figure 1. The bed frame comprises a rear end section 3, which ishingedly connected at 4 with the next section 5, which may be pivoted insaid end portion and be hingedly connected with one or more furthersections of the bed frame. These sections are preferably made of metaltubes, and they may be provided with a resilient bed bottom of anysuitable type not shown in the drawing. The end section 3 is composed oftwo longitudinal frame portions and an end frame member 6 adapted toslide on two guide members I, when the section 3 during the unfoldingoperation is raised from a bottom position corresponding to Figure 2 toits upper position shown in Figure 1. In this position the end of thesection 3 is supported by the guide members I carried by the backportion.

The longitudinal frame membersof section 3 are provided with a lockingdevice in the form of an angle arm of a square cross section. The

lower end thereof consists of a pivot H! passing through the metal tubeof the section 3. It rests with a shoulder 9 thereon and is below theframe member provided with a locking nut H. The pivot is mounted in asubstantially vertical position, and the upper portion of the arm isbent at a right angle. A plate spring I2 is fastened to the upper end ofthe angle arm 8 and forms a lateral extension thereof.

When the bed frame is unfolded and the section 3 is in the positionshown in Figure 1, the horizontal portion .of the locking arm 8 is to beturned outwardly to rest upon the frame member 2. The inner end ofsection 3 is thus carried rigidly by the frame portion 2 and is thus ofno obstacle.

When folding the bed frame together the looking arm i9 is to be turnedwhereby the end section 3 is released, and the spring [2, which servesas a handle for the locking arm, now extends over the bed It provided onthe bed frame and exerts a pressure thereon so as to keep the bed inposition during the folding operation.

The form of execution shown in the drawing is only an example of theperformance of the invention. and modifications are therefore possiblewithin the scope of the invention.

Instead of the horizontal portion of the locking arm resting on theupper surface of the frame section 3 the locking arm may be providedwith other locking means such as a tongue engaging a slot in the framemember 2.

I claim:

1. In a folding bed, a main frame comprising two end members and a backmember connected thereto, a bed frame comprising a plurality of sectionshingedly connected one to another, one of which sections forms an endsection, a sloping guide member secured to said back member and adaptedto raise the end frame portion of said end section, from a lowerposition within the folding bed to an upper position when the bed frameis unfolded, and a locking device pivoted in a longitudinal frameportion of said end section, said locking device resting when turnedinto one position against one of said end members for locking said endsection of the bed frame when said frame is unfolded but which lockingdevice releases said end section when the looking device is turned toanother position.

2. In a folding bed, a main frame comprising two end members and a backmember connected thereto, a bed frame comprising a plurality of sectionshingedly connected one to another, one of which sections forms an endsection, a sloping guide member secured to said back member and adaptedto raise the end frame portion of said end section from a lower positionwithin the folding bed to an upper position when the bed frame isunfolded, and a locking device havin a vertical pivot passing through atubular longitudinal frame portion of said end section and an upperlocking arm forming a substantially right angle to said pivot andadapted to rest in one position against one of said end portions forsupporting said end section when the bed frame is unfolded but releasingsaid end section when the locking arm is turned to another position.

3. In a folding bed, a main frame comprising two end members and a backmember connected thereto, a bed frame comprising a plurality of sectionshingedly connected one to another, one of which forms an end section, asloping guide 'member secured to said back member and adapted to raisethe end frame portion of said end section from a lower position withinthe folding bed to an upper position when the bed frame is unfolded, anda locking device pivoted in a longitudinal frame portion of said endsection and having an upper locking arm adapted to rest in one positionagainst one of said end portions for supporting said end section whenthe bed frame is unfolded but releasing said end section when thelocking arm is turned to another position, and said locking devicehaving a laterally extending resilient extension adapted to rest againstthe bed when the locking arm is turned to a released position.

4. In a folding bed, a main frame comprising two end members and a backmember connected thereto, a bed frame comprising a number of sectionshingedly connected one to another, one of which forms an end section, asloping guide member secured to said back member and adapted to raisethe end frame portion of said end section from a lower position withinthe folding bed to an upper position when the bed frame is unfolded, anda locking device pivoted in a longitudinal frame portion of said endsection and having an upper locking arm adapted to rest in one positionagainst one of said end portions for supporting said end section whenthe bed frame is unfolded but releasing said end section when thelocking arm is turned to another position, and said locking devicehaving a laterally extending resilient extension adapted to rest againstthe bed when the locking arm is turned to a released position and to belocated along the said end member when the locking arm is turned to alockin position.
